Answer 1

@amistre64 Can you check my answer please?

Answer 2

(-1/3)x + 3 = x - 1 Is my answer correct? @Data_LG2

Answer 3

the equation of the graph with positive gradient is (1/3) x - 4

Answer 4

That's not one of my answer choices

Answer 5

-4?

the y-int is -3
so she must be right

Answer 6

sorry i'm just dealing with one line at a time
it should be (1/3)x - 3

Answer 7

So i'm right?

Answer 8

oh yeah, "-3" not "+3"
sorry made a mistake too :P

Answer 9

the equation with the negative slope is
-x + 1

(1/3)x - 3 = -x + 1
(1/3)x - 3 = 1 - x

Answer 10

(-1/3)x + 3 = –x – 1 is this the answer then?

Answer 11

postive 1/3 not negative

Answer 12

(1/3)x – 3 = –x + 1 so this is the answer?

Answer 13

y=mx+b
m=slope
b=y-int (0,y)

first line, y-int is +1
2nd line, y-int is -3

slope. Pick two points from each line and plug them into the slope formula.
\(\sf \Large m=\frac{y_2-y_1}{x_2-x_1}\)
Tell us what you get and please don't try to guess again.

Answer 14

yes

Answer 15

Oh ok thanks! :) @welshfella @Data_LG2
